Rotary machine

ABSTRACT

The present invention may be used in pumps and hydraulic engines and increases the functional capacities of rotary machines. This invention relates to a rotary machine comprising a body in which an adjustment member is mounted so as to be capable of displacement along the rotation axis. A plurality of systems, that define the axial and mutual disposition of sliders, are mounted so as to be capable of changing their position relative to the rotor and the body, and are cinematically connected to the adjustment member. The sliders are mounted so as to be capable of changing their position upon displacement of the adjustment member.

BACKGROUND OF THE INVENTION

The invention refers to mechanical engineering and can be applied inpumps and hydraulic motors. Liquids and gases are used in the rotormachine as the working medium. Under the term “regulation” theadjustment of the machine for a certain volume of the working volume ismeant Hence in case of application of the machine as a pump it ispossible to change the flow rate and in case of using it as a hydraulicmotor—to change rotation speed on the shaft. A rotor machine is known(application for European patent No 0261682 that is composed of a rotorlocated inside the housing. The rotor has radial slots in which slidevalves are mounted arranged in such a way that they can shift radially.In radial direction the working chamber is restricted by the rotorsurface and the internal peripheral surface of the housing that haselliptical cross-section. During rotation of the rotor slide valves aremoved out of the rotor under the action of centrifugal forces and arepressed against the internal surface of the housing which serves as acomponent assigning radial mutual position of slide valves and theyslide over this surface thus creating low- and high pressure zones inthe working chamber.

In the axial direction the working chamber is restricted by two endmembers one of them being in contact with one of the rotor end and ismovable in the axial direction and the second one being mounted on theother side of the rotor and rotates together with it This second endmember (referred to in the said application as the member that changesthe capacity of the machine) has a cavity into which a part of the rotorwith slide valves in inserted. The length of the part that is notinserted into the cavity of the second end member determines the axiallength of the working chamber.

By shifting the first end member movable in the axial direction therotor can be moved into the cavity of the second end member to a greateror smaller length thus changing the length of the working chamber andaccordingly its volume.

Similar machines in which slide valves move inside the rotor in radialdirection are described in international application No 88/02438 and inBritish application No 2207953. In these machines it is also possible tochange the volume of the working chamber however unlike the machinedescribed above the volume of the working chamber is varied not bychanging its axial but the radial dimension. E.g. in the machinedescribed in British application No 2207953 slide valves mounted insidethe rotor are pressed by springs to the internal profiled surface of thering that encircles the rotor. This ring is fitted with a segmentmovable in radial direction and located in the zone between the inletand outlet openings of the machine. Radial position of the segmentdetermines the volume of the working chamber of the machine. In therotor machine described in international application No 88/02438 therotor is installed so that it can slide in the housing, the internalperipheral wall of which has elliptical cross-section in the directionperpendicular to the axis of rotation. The disadvantage of rotormachines with radially moving slide valves are difficulties connectedwith provision of tightness of the working chamber as the workingchamber has surface areas with varied curvature.

The rotor machine (British Application No. 1469583) is chosen as theclosest analog. This machine contains a rotor with radial slots in whichslide valve moving along the rotation axis of the rotor are mounted. Theworking chamber of the machine is restricted in the axial direction byopposite ends of the housing and the rotor and in radial direction—byareas of the surface of the rotor shaft and the internal cylindricalsurface of the housing located between the said ends of the rotor andthe housing. A partition is installed inside the working chamber thatseparates the inlet and outlet openings and it is in sliding contactwith the adjoining rotor end and the rotor shaft. As the rotor rotatesslide valves make a complicated motion rotating together with the rotorand moving simultaneously along its axis of rotation. When slide valvesare remote from the partition they enter into the working chamber out ofthe rotor. As the slide valves approach the partition in the process ofrotation of the rotor they move gradually into the rotor and occupy sucha position when they do not project over the rotor end. In this positionthey pass the partition without touching it when the rotor rotates.

In order to provide axial movement of slide valves special members aremounted in the rotor slots that assign axial mutual position of slidevalves—it is a groove cut in the internal surface of the housing withprofiled surface into which slide valve edges enter. This sinusoid—likegroove plays the role of a master cam and assigns the character of theaxial movement of slide valves in slots of the rotor during itsrotation.

The disadvantage of the machine described in British application No1469583 is that the volume of the working chamber cannot be changed. Asit was mentioned above the working chamber is restricted from one sideby the end of the rotor that is non-movable in the axial direction andfrom the other side- by the end of the housing. Hence the machine ofthis type can be designed so as to work with maximal efficiency underdefinite operational conditions. When the conditions are changed suchmachine will work less efficiently or even unsatisfactorily.

SUMMARY OF THE INVENTION

The purpose of this invention is to develop a regulated rotor machinewith reciprocating motion of slide valves along the rotation axis of therotor which enables to extend functional capacities of rotor machineswith such motion of slide valves and to avoid disadvantages typical formachines with radial motion of slide valves.

The problem is solved in the following way. The rotor machine containsthe housing with inlet and outlet openings, the rotor mounted inside thehousing with at least two slide valves that can move in the directionalong the axis of its rotation; the working chamber restricted in thedirection along the rotation axis of the rotor by its first end; thepartition inside the working chamber fixed on the internal surface ofthe housing so that it separates the inlet and outlet openings and is insliding contact with the said rotor end; members that assign axialmutual position of slide valves and according to the invention isprovided with a regulating member which is fixed inside the housing andis free to move in the direction along the rotation axis of the rotor.The regulating member restricts the working chamber along the rotationaxis from the opposite side and is connected with the members thatassign the axial mutual position of slide valves. The members thatassign the axial mutual position of slide valves are mounted so thatthey can change their position with respect to the housing with therotor and are connected cinematically with the regulating member; theslide valves are installed so that they can change their position withrespect to the rotor when the regulating member is in motion; in thiscase slide valves located inside the working chamber are in slidingcontact with the end of the regulating member and separate the inletopening from the outlet one. The length of axial projection of the slidevalve is the distance between the rotor end to the slide valve end,moved out of the rotor into the working chamber of the machine. Thechange of the volume of the working chamber in the proposed rotormachine is effected due to the change of its axial length when theregulating member is moved to one or another side with respect to therotor. Besides to balance the load on the second rotor end opposite therotor end that faces the working chamber and to exclude the influence ofthe slide valve volume on the uniformity of the machine feed and itscapacity the machine can be fitted with a supporting and distributingmember that is fixed inside the housing and is in sliding contact withthe other rotor end. Two cavities separated from each other are providedin the said end of the supporting and distributing member. One of thesecavities is connected by a channel with the inlet opening and the otherone—with the outlet opening.

In order to reduce hydraulic losses during reciprocating motion of slidevalves, to reduce their weight and to balance the force of pressureacting on the slide valve end facing the working chamber and theopposite end a through opening is provided in each slide valve whichbegins on the slide valve end facing the working chamber and ends on theslide valve end opposite to the said slide valve end.

In order to reduce axial vibration of the rotor through channels can bemade in it them that connect opposite rotor ends between two adjacentslide valves.

Like machines of other types this machine can be of multi-chamber designand have more than one partition and regulating member the number ofcavities provided in the end of the supporting and distributing memberbeing increased accordingly.

FIG. 2 shows a development of the rotor and side cylindrical surface ofthe machine.

FIG. 3 shows a development of the rotor and side cylindrical surface ofthe machine with channels through the slide valves.

DETAILED DESCRIPTION OF THE INVENTION

The rotor machine (FIG. 1) contains housing 1 with covers 2 and 3. Rotor5 on shaft 4 is placed in the middle of the cylindrical opening drilledin housing 1. Radial slots 6 are provided over the whole length of rotor5 with sliding valves 7 inserted into them so that they can performreciprocating motion along the rotation axis of the rotor. The number ofsliding valves can be two or more. There are special members locatedinside the housing that assign axial mutual position of sliding valvesin slots 6 of rotor 5 and the length of their maximal axial travel outof rotor 5 into the working chamber.

According to the design presented in the drawings these members are madein the form of hollow cylinder 8 on the internal cylindrical surface ofwhich an enclosed curvilinear groove 9 is cut. This hollow cylinder 8 isfitted on rotor 5 the external radial surface of rotor 5 and theinternal cylindrical surface of hollow cylinder 8 being in slidingcontact. The cylinder is fixed inside housing 1 so that it can slideover the surface of rotor 5 along its rotation axis not rotatingtogether with the rotor. Beside each sliding valve 7 has projection 10which enters recess 9 of hollow cylinder 8 and is in sliding contactwith it. The machine is provided with partition 11 fixed on the internalsurface of the housing, particularly it is fixed on cover 2 of thehousing. Partition 11 adjoins the first end of rotor 5 that faces thiscover 2 of the housing and shaft 4 of the rotor 5 which are in slidingcontact. Recess 9 is made so that sliding valves 7 located opposite theend of the partition 11 adjoining the first end of rotor 5 enter rotor 5to an equal length and some sliding valves that are remote frompartition 11 are moved out of the rotor 5 and are in sliding contactwith the end of regulating member 12 thus separating the inlet opening16 from the outlet opening 17. Regulating member 12 is placed betweenhousing cover 2 and the first end of rotor 5 so that it can move alongthe rotation axis of rotor 5. Regulating member 12 restricts the axiallength of the working chamber. The axial length of the working chamberis the distance between the end of regulating member 12 and the end ofrotor 5 which face each other.

According to the design regulating member 12 presented in the drawing ismade as a disk with the central opening through which shaft 4 of rotor 5passes and has a cutout through which partition 11 passes. This disk isplaced so that it can slide over shaft 4 along its rotation axis notrotating with it. Regulating member 12, particularly disc with a slot isfixed to the end of hollow cylinder 8 and they can form a singlecomponent of the machine. Setting rod 13 is fixed to regulating member12. This bar can move along the rotation axis of rotor 5 and projectsout of the housing.

Thus the cavity of the working chamber is restricted in the directionalong the rotation axis of rotor 5 by the first end of rotor 5 and theend of regulating member 12 that faces the first end of rotor 5 and inthe radial direction is restricted by radial insulation members. It isonly insulation members that prevent the working medium from flowing outof the working chamber. According to the design radial insulationmembers presented in the drawings are the surface of shaft 4, thesurface of partition 11 and the internal surface of hollow cylinder 8.

Supporting and distributing member 14 is fixed on cover 3 of thehousing. This member can form a single component with cover 3. The endof supporting and distributing member 14 is in sliding contact with thesecond end of rotor 5. There are two separated cavities 22, 26 in theend of the supporting and distributing member 14. One of the cavities 22is located opposite the working chamber cavity 28, which is connectedwith the inlet opening 16. The cavity 22 is connect with the cavity 28by a channel 20. The second cavity 26 is located opposite the workingchamber cavity 30, which is connected with the outlet opening 17. Thecavity 26 is connected with the cavity 30 by another channel 24.

Besides through channels 15 are made in rotor 5 to connect opposite endsof rotor 5 between adjacent sliding valves 7 (see FIG. 2).

The machine can work in the pump mode and in the hydraulic motor mode.The machine operates in the pump mode in the following way. The volumeof the working chamber is assigned by setting rod 13 with respect tohousing cover 2 and if necessary it can be changed during operation.Accordingly regulating member 12 occupies a certain position withrespect to the first end of rotor 5 and restricts the axial length ofthe working chamber and hence—its volume. Hollow cylinder 8 connectedwith regulating member 12 has curvilinear groove 9 into whichprojections 10 of sliding valves 7 enter. As regulating member 12 is inmotion cylinder 8 shifts accordingly and assigns the length of maximalpenetration of sliding valves inside the working chamber. After startingthe machine when rotor 5 begins to rotate projections 10 of slidingvalves 7 start to slide over curvilinear groove 9 of hollow cylinder 8and make reciprocating motion along the rotation axis of rotor 5 whichis transferred to sliding valves 7. Groove 9 is made so that the motionof slide valves 7 per revolution of rotor 5 is characterized by thefollowing cycle. Sliding valve 7 located opposite the end of partition11 is moved into rotor 5. As slide valve 7 shifts off partition 11 itstarts moving out of slot 6 into the cavity of the working chamber andat a certain moment its end will touch the end of regulating member 12.Then the end of slide valve 7 slides over the end of regulating member12 and does not move axially. Next as the valve approaches partition 11it begins to move into slot 6 of rotor 5 very smoothly and by the momentof passing through partition 11 it will be completely moved into rotor5.

When sliding over the end of regulating member 12 slide valve 7separates the working chamber into two cavities; in one of them the lowpressure zone is formed in the other cavity- the high pressure zonewhich are connected respectively with the inlet and outlet openings ofthe machine. The inlet and outlet openings are not shown in the drawingnot to complicate it. The volume of the working medium contained betweentwo adjusting slide valves 7 that slide over the end of regulatingmember 12, is transferred from the low pressure zone into the highpressure zone. The force of pressure acting from the working chamberside against the first end of rotor 5, is compensated by supporting anddistributing member 14 the end of which is in sliding contact with thesecond end of rotor 5. Two separated cavities provided in the end of thesupporting and distributing member 14 are located so that one of them isopposite the cavity of the working chamber with the low pressure zoneand the other—opposite the cavity with the high pressure zone. Theopposite cavities of the working chamber and supporting and distributingmember 14 are connected by a channel and form opposite lying low- andhigh pressure zones that compensate the axial load on the end of rotor5. During rotation of rotor 5 as slide valve 7 moves off partition 11 itpenetrates into the cavity of the working chamber with the low pressurezone and brings its volume into it However on the other hand exactly thesame volume of the working medium fills slot 6 in which this slide valve7 is located out of the opposite cavity of supporting and distributingmember 14 with which this slot 6 is connected. Next the end of slidevalve 7 located in the working chamber slides over the end of regulatingmember 12 and the end of the supporting and distributing member 14sliding over the second end of rotor 5 shuts off slot 6 in which thisslide valve 7 is located, in axial direction and separates it fromcavities provided in the end of supporting and distributing member 14.As slide valve 7 approaches partition 11 slide valve 7 begins to enterrotor 5 and the volume of the displaced working medium out of the cavityof the working chamber with high pressure zone will be reduced by thevalue of the part of the volume of slide valve 7 which moves into rotor5. But exactly the same volume of the working medium is displaced intothe cavity of the supporting and distributing member 14 located oppositethe cavity of the working chamber with high pressure zone as slot 6 inwhich this slide valve 7 is located is connected with the cavity ofsupporting and distributing member 14 which is connected by the channelwith the opposite cavity of the working chamber with the high pressurezone. In this way influence of the volume of slide valves 7 on thecapacity and uniformity of the feed is compensated. Working as ahydraulic motor the machine operates in the same way as other types ofreversible pumps.

In order to reduce hydraulic losses during reciprocating motions ofslide valves, to reduce slide valve weight, and/or to balance the forceof pressure acting on the slide valves, as shown in FIG. 3, a throughchannel (18) may be provided in each slide valve. Each channel (18) maybegin on the slide valve end facing the working chamber and end on theslide valve end opposite to the said slide valve end.
